Significant low snowfalls over Tasmania this week

 

  • A deep low pressure system south of Tasmania is bringing cold temperatures, showers and gusty conditions this week.

 

  • Snow settled to 100m to 200m about the West, the Central Plateau and the far south on Tuesday morning, but will rise to 400m during Tuesday evening.

 

  • The snowline is expected to lift to 1000m during Wednesday, then lower again to around 200m Thursday evening behind a cold front in the afternoon.

 

  • Significant snow depths are likely about the west, Central Plateau and far south over the course of the week which may lead to prolonged road closures.

 

  • Isolated stations in the southeast recorded their coldest night in July 24, 2016. These were 2.2°C at Cape Bruny and Maatsuyker Island, 3.2° at Maria Island and -6.4° on Mt Wellington/kunanyi.

 

  • Many stations have reported a very cold September day, however daily observations will not be finalised until 9am Wednesday.
